[solved] gspca_zc3xx possible options in Mint lxde 12?
Posted: Thu May 03, 2012 4:24 pm
Good day board!
I have been looking information about how to control certain aspects of my webcam that is working and using gspca_zc3xx driver.
From latest gspca_zc3xx.h from author's site (http://moinejf.free.fr/) I can see many interesting words like min_gain max_gain global_gain and such. Also from some odd site I found gspca_zc3xx.c which had gamma and exposure related words in it.
Still I have had no luck finding what are all possible words to use for options gspca_zc3xx line, I found one single mentioning that with more recent drivers it would be just force sensor setting and nothing else, surely this can't be right?
Issue is that automatic fails with my webcam, I have it set to point into scary outside world and image looks fine up until 2pm, when it suddenly becomes white and to cure that nothing seem to help, not rebooting, not reloading driver, it just stays white until evening comes and light level goes enough low. auto exposure fails to remember that it can do lot better during bright illumination, so I would like to force it to certain parameters that I know will work.
I use software called Motion that have some ability to control webcam, but if I don't get automatic functions turned off it can't of course do so well.
So far any keywords for options that I have found produces invalid symbol and dmesg shows that option was not understood/support by driver. For setting options I made options file into /etc/modprobe.d/, which it warns about that it should be options.conf or something like that, maybe there even is proper file to put those options already, but I found only this old method from internet and as it seem to work I have not tried to search more, I spent already two full days on searching this and it is bit of let down to now find how to do this as with windows all I would need to do is few clicks of mouse, but then again where is fun in that?
Perhaps here someone has found list of all possible keywords that should work?
Camera with issue is probably that E3500, I think, can't remember which is which, but the issue is one that is not sphere type, there is two cams on that particular machine as shown in here:
Bus 001 Device 002: ID 046d:09a4 Logitech, Inc. QuickCam E 3500
Bus 002 Device 002: ID 046d:08da Logitech, Inc. QuickCam Messanger
edit: With modinfo gspca_zc3xx command I get long alias list and then
Does modinfo works so that if there would be other parameters to set it would show them, so that there really are no anything else in my driver than that force sensor?
